ACCURACY ASSESSMENTS OF PAN-SHARPENED IMAGE FOR BENTHIC HABITATS MAPPING

Geoplanning: Journal of Geomatics and Planning, 2017
Image-sharpening process integrates lower spatial resolution multispectral bands with higher spatial resolution panchromatic band to produce multispectral bands with finer spatial detail called pan-sharpened image. Although the pan-sharpened image can greatly assist the process of information extraction using visual interpretation, the benefit and ...

Improvement of Image Alignment Using Camera Attitude Information [PDF]

, 2001
We discuss a proposed technique for incorporation of information from a variety of sensors in a video imagery processing pipeline. The auxiliary information allows one to simplify computations, effectively reducing the number of independent parameters in

Developing ocean literacy through a relational model: Exploring outcomes of a place‐based ocean education programme in primary schools

People and Nature, EarlyView.
Abstract Schools are a common place where the younger generation can develop their understanding of the ocean and acquire the skills needed to become responsible and knowledgeable ocean advocates. Grounded in a relational ocean literacy model, this study examined outcomes of a place‐based programme integrating picture books, beach excursions and ...

Acoustic signatures of the seafloor: Tools for predicting grouper habitat [PDF]

, 2006
Groupers are important components of commercial and recreational fisheries. Current methods of diver-based grouper census surveys could potentially benefit from development of remotely sensed methods of seabed classification.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

People and Nature, EarlyView.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Selecting the best habitat mapping technique: a comparative assessment for fisheries management in Exmouth Gulf

Frontiers in Marine Science
A spatially explicit understanding of marine benthic habitats is essential for sustainable marine resource management. While advances in remote sensing, acoustic methodologies, geostatistical modelling, and predictive species distribution models have ...

Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

Classification of Benthic Habitat Based on Object with Support Vector Machines and Decision Tree Algorithm Using Spot-7 Multispectral Imagery in Harapan and Kelapa Island [PDF]

, 2018
The research of object based image classification (OBIA) with machine learning algorithm for high resolution image in Indonesia is still limited especially for coral reef mapping, therefore further research needed for comparison in method and application
